Stars: Oscillations

Scientific paper

In order to interpret the ground-based observations of solar-like stellar oscillations and prepare the scientific exploitation of future spatial asteroseismic observations, we have studied the theoretical properties of the frequencies of possible models for a given stellar target, taking into account its observational constraints in the Hertzsprung-Russell diagram. We have computed a set of "calibrated" stellar models satisfying these constraints for a star of solar metallicity. We present some results on the sensitivity of the oscillation frequencies to the description of the convective transport and to physical processes entering in the stellar modeling, like core overshoot. We compare the seismic properties of our models with the observations of Procyon by Martić et al. (2001).
